To all whom ii may concern:

' 'Be it known that I, ARTHUR E. ErIGLA ND,

" of Boston, in the county of Sufi'olk and State of Massachusetts, haveinventedcertain new and useful Improvements in Stud and,SocketFasteners, of which the following %is a specification. 1

I This invention relates to fasteners for;car= riage curtains, glovesand other articles, one member of the fastener being a socket which hasan inelastic or'rigid wall, and the. other member'a stud adapted toenter the socket and engage the wall thereof in such'manner as" to-resist"separation of the members.

"The invention has for its object to provide a construction whereby,when the members zare interengaged the stud member will. be positivelylocked to thesocket member: so

thatjit cannot be withdrawn therefrom until-the stud member has beenunlocked from the socket member by a specialdeyice' pr0-vvidedffo'r'tli'at purpose. v The invention consists in improvementswhich-Twill now proceed t0-describe 1 a.nd lclaim. 9 0f the accompanyingdrawings. forming part of the specification Figure 1 re resents a sideview'of a. stud .member' em odyin my-"i'invention. -"-.Figl 1 2?represents an view showing, said memberengagedwith an -inelasticsocketmember: represents a section on the line 3-3 of-Fig; 2, showing the.stud member locked to the socket member.

- inclusive, saidmembers being "shown ap plied to the parts which carrythem and interlocked with each other.

The same reference charfahters indicate the same parts in all thefigures.

Referring for the present to Figs. 1 to 5' inclusive, the stud memberwhich is shown separately in Fig. 1 includes an attaching base 12, and atubular body projecting there- "fronn said body being provided with ashoulder 13 adapted to. engage the wall 14 of an orificeformed innssocket member 152 shown separately in Fig.- 5. The attaching.

base 12 and the socket member 15 'may be= adapted for attachment 'in anydesired way tothe parts 16 and 17 (shownby dotted lines in Fi s. 3and-4) which carry said members. when the fastener is used to (3011-.nect parts of a. glove or other likea'rticle,

the parts 16 and -17 areboth flexible. When the fastener is used tosecure carriage cur- 'tains, etc.,lthe part 16- which carries thestud-member may a rigid part of the top frame of 'a carriage;

gz In-the embodiment of invention here described, the attaching-base andthe body pf jthe stud member are integral with each other and may becast. swaged, or otherwise formed fromcany suitable metal. The body ,ofthe stud member isIOngitudinalIy subdivided byjslots 16 into a pluralityof resilient sectonslfl which are oi segmental form in cross'sectionfthe outer side- 0f each section carrying a isegment' oftheshoulder 13. The sections 17 tare adapte tonormally spring inward, asshown by -41 ig., 4, romance .the diameter of the shoulder'13 tothejininimum.

its diameter being less than "that of the wall 18 represents aplungenwhicll is movable displacing portion and with. acylindricalsupporting portion 21'. The inner sides .of

the resilient sections 17- are recessed to rcceive the portionsQOaiid 21of the plunger, a's shown by. Fig. 4, so that when the plunger is pushedinwardlythe sectipnsarepermitted port the same against inward movement.

When theshoulder 13 is thus expanded its diameter is reater than that ofthe socket wall 14, so tdlat the stud and socket members are inseparablyinterlocked.

The plunger 18 projects from the outer end of the stud membersufiiciently to enable pressure to be applied to' it to move it from theposition shown in Fig. 3 to that shown in Fig. 4. The .inner end of theplunger is provided with a head or enlargement 22,

constituting a stop member which cooper ates with inwardly projectingstop members 22 on the sections 17 in limiting the outward movement ofthe plunger and preventing its separation from the stud member. Theinner end of the sprin 19 bears on a seat 23, at the inner end 0 thebody portion of the stud member.

From the foregoing it will be seen that before the stud and socketmembers canbe brought into engagement with each other, the plunger 18must be pressed inwardly, and that, after said members have beenengaged, they cannot be separated until the plunger is again pressedinwardly.

Referring now to Figs. 6 to'lO inclusive, which show a sheet metalconstruction, 12 represents the attaching base of the stud member, 13the shoulder of the same, and 17* the resilient sections, these partsbeing all formed from a sheet metal blank by a series of suitableoperations and tools, the sections 17 being rolled inwardly at theirouter 'ends, as at 25 (Fig. 10), to bear onthe plunger 18. The innerportion of the tubular body is contracted at 26 to form a seat for thespring 19. The attaching base 12 is shown as provided with a pluralityof flexible prongs 27, which are passed through orifices 28 (Fig. 9)formed for their reccp-' tion in a plate or washer 30. the base '12being placed upon one side of the carrying part 16, the prongs 27 forcedthrough said part-and through the plate 30, which is placed on theopposite side of the part 16, the springs 27 being clcpched on the underside of the plate 30, as shown in Fig. 10. In this embodiment oftheinvention the socket member includes in addition to a p ate 15 having aninelastic socket wall 14: adapted to engage the shoulder 13, a casing 31ermed to cover the outer portion of the stud member.- Said casing, whichis of sheet 7 metal, is fonned to bear on the outer side of the carryingpart 17' and has flexible prongs 32 which are formed through the part17" and are clenched upon the under side of the annular plate 14, whichin this case is provided with slots 33 to receive the prongs 32. Thecasing 31'hasat its outer end an inwardly turned flange 34:, whichconfines a push piece 35 bearing on the outer end of the plunger .18.Said push piece is movable '1 between the flange 3d and a suitable stop36 within the casing, and is adapted to receive pressure from theoperators thumb or finger and to transmit the same to the plunger 18 tomove the latter inwardly and cause the contraction ofthe shoulder 13.When the plunger is projected it holds the push piece 35 in its outwardposition;

1. A stud and socket fastener comprising atubular stud member having atits inner end portion an attaching'base, and at its outer end portion anexp'ansible socket-engaging shoulder which is automatically con-'tracted, and a spring pressed locking plunger adapted to automaticallyexpand the said shoulder and positively hold it expanded, said plungerbeing displaccable to permit the automatic contraction of theshoulder,the stud member and plunger being r0- vided with complementalstop memers which limit the outward movement of the plunger and prevent itsseparation from the stud member and a socket member having aninexpansible wall formed to engage the expanded shoulder and to passover the shoulder when the latter is contracted.

2. A stud and socket fastener comprising a stud member having anexpansible socketenga ging shoulder which .is automatically contracted,and a spring pressed locking plunger adapted to automatically expand thesaid shoulder and positively hold it expanded,'said plunger beingdisplaceable to 4 permit the automatic contraction of the shoulder, anda socket member having an inexpansible wall formed to engage theexpanded shoulderand to pass over the shoulder when the latter iscontracted, said Socket outwardly and expand the shoulder, and 5 Intestimony whereof I haw: afiixed my supporting portion formed to lookthe secsignature, in presence of two witnesses.
